Fourth Ventricular Rosai-Dorfman Disease Mimicking Intraventricular Tumor in Young Adult: A Rare Case Report.

Rosai-Dorfman disease (RDD) or sinus histiocytosis with massive lymphadenopathy can present with or without systemic disease. It is a benign histioproliferative disorder characterized by generalized lymphadenopathy, weakness, anemia, and rarely extranodal involvement. While RDD most commonly affects lymph nodes, extranodal involvement of multiple organs has been reported, including the central nervous system (CNS).

Transanal rectopexy for external rectal prolapse.

Purpose: The surgical management of patients with full-thickness rectal prolapse (FTRP) continues to remain a challenge in the laparoscopic era. This study retrospectively assesses a cohort of patients undergoing a transanal suture sacro rectopexy supported by sclerosant injection into the presacral space under ultrasound guidance.

Methods: Patients with FTRP underwent a sutured transrectal presacral fixation of 2/3 of the circumference of the rectum from the third sacral vertebra to the sacrococcygeal junction through a side-viewing operating proctoscope.
